COMBINED CHIMNEY, FURNACE, AND VENTILATOB.

Application filed-February 12, 1925. Serial No. 8,763.

To all whom/it may concern: pit and another branch 14 extending into Beit known that I, ,EDWARD DUDLEY the air heating space 6, said brancheshav- Liiwis, a citizen of Ythe United States, reing appropriate valvesor dampers 13 and siding at Elmira, in the county of Chemung 14',respectively. Any desired means, such and vState of New York, haveinvented ceras the blower 15 ,may be used to direct air tain new anduseful Improvements in a through the piping, and tlie travel of thisCombined Chimney, Furnace, and Ventiair is of course controlled by thevalves or lator: and I do declare the following to be dampers 13 and 14.

a full, clear, and exact description of the The inner and outer walls 4and 5 are invention, suoli as will enable others skilled preferably ofVthe same height, and their upiii the art to which it appertains to makeper ends support a horizontal plate 16 havand use the same. ing a lange17 at its edge which surrounds Itis well known that a great deal of heatthe wall 5 and may assist in holding a jacket is exhausted and wastedthrough the ordi- 1 8 around said wall if such jacket is denai-ychimneys and stacks from furnaces and sired. The plate 16 is providedwith an other forms of heateis. It is the primaryminnci' relativelysmall upstanding collar 19 object of my invention however to providewhich communicates with the interior of a new and improved Constructionwhereby thel inner wall 4, and said plate is also prothere will bepractically no waste heat, the i'ided with an outer relative yrlargeupstandliot gases discharged from the burning fuel, 111g 6911er 20,suitable heat escape openings being utilized substantially throughouttheir 21 being fOrmcd through the plate, between travel, t0' heat air,Such air being in turn the inner and outer collars. An outer comused toheat the building in which the im- Paratlfely large pipe 22 is engagedat its moved Structure is Sed lower end with the collar 2() and extendsYA further object is to provide for use of nPWaIflly from the Plate 16through Open the heating system as a cooling and ventilngs 23 1n tllenumerous flQOlS 0f the build' lating system in warm weather. lngf and anInner Smalle?l Pipe 2 4 lS engaged lVth the foregoing in view, theinvention Wltll the Cpllfil' 19, Saul lIlIleI P1P@ being C0- resides inthe novel subject matter hereineXtrensive 1 n length with the outer pipe22. after described and claimed, the description The lWO P11395 nr? heldln Slmcd relatlon by being supplemented by the accompanying Stay-bolts25 positioned at desired intervals drawing, in which a verticalsectional view and the SPaCB 26 between Said plipes constic makes useshown, installed within 'a building.

In addition tocontrolling The furnace 1 comprises an inner conthe discharge of hotair, these valves or tinuous wall 4 and an outer continuous wallClampels may bQ'USed t0 SlIIillaIly COIltIOl 5, an air heating space 6being provided becool air when the furnace is out of operatween the twowalls. Within the wall 4, a tionin warm weather and the blower 15 isgrate 7 has ybeen shown for burning solid utilized to direct a blast ofair into the space fuel, and a fuel door is indicated at 8, it 6,between the inner and outer Walls4 and 5 heilig understood however thatgas or oil ofthe furnace. -'I`hus, with a single system, could beconsumed instead of solid'fuel, if heating may be eleoted to a highstate of desired. In the construction shown, an ash perfection'in coldweather, and cooling and pit is of course 'provided under thegrate,Ventilating may be eiected in Warm Weather. Resting upon the upper endsof the pipes the usual functions, and 11 refers to a door ing ilangesvor collars 30 and 31 whic enor giving access tovsaid pan. gage said'pipes 22 and 2A, respectively, the

I prefer to employ air-supply piping 12 collar 31 being preferablyrather long to having a breach l@ extending iet@ @head1 proud@ a, S119101111.22 efenvly @klug-Care of expansion and contraction of the innerpipe 24, in which connection, it may be stated that the drawingillustratessaid pipe when expanded to the maximum, whereas cooling andcontraction of said pipe will of course cause it to lower somewhat fromthe plate 29. In order that the stay-bolts will not. interfere withunhampered expansion and contraction of the pipe 24 in a verticaldirection. these bolts are preferably passed only through the outer pipe22 andI have their inner ends slidably engaged with said pipe 2l.

The cap plate 29 supports a suitable chimney 32 which extends throughthe roof of the building and may well be formed of brick, although thisis not essential, as any desired materials may be used. The pipe 24 isplaced in rather restricted communication with the chimney by adischarge neck 33 .at the center of the plate 29, said neck extendingupwardly into the chimney so that Athere is no possibility of the lattershifting laterally with respect to the remainder of the system.

By providing the novel construction shown and described, or asubstantial equiv-` alent thereof, a system is provided which willutilize heat heretofore going to waste up the chimney or stack, andconsequently great economy in fuel is effected, as well as obtainingmoreheating eiciency. Moreover, the invention is readily convertible foruse as cooling and Ventilating means in hot weather. Thus` with a singlesystem two needs are elfectively overcome. y

As excellent results may be obtained from the general constructiondisclosed, it may well be followed. However,- within the scope of theinvention as claimed, modifications may of coursey be madee I claim:

1-. A heating system comprising a furnace having spaced inner and outerwalls and an air inlet into the space between said walls, means withinthe inner wall permitting heating thereof to in turn heat the airbetween the two walls, an outer pipe rising from the outer wall andadapted for passage through an opening or openings in the Hoor or floorsof the building in which the system is used, an inner pipe' within saidouter pipe in spaced relation. with the latter and rising rigidly fromthe aforesaid inner wall to form an exhaust gas escape therefrom, a capplate resting on at least the outermost of said pipes and connected withboth of said pipes,

and a chimney rising from and supported by said cap plate, said outerpipe having air escape openings.

2. A structure as specified in claim l; said chimney being formed as aseparate part from said cap plate and the latter being provided with anupstanding discharge neck received in said chimney to hold the latter inproper relation with the plate.

3. A heating system comprising spaced inner and outer walls and an airinlet for the space between them, means within the inner wall permittingheating thereof to in turn heat the air between the two walls, ahorizontal plate resting on the upper ends of said walls and having heatdischarge openings betweenthem, collars rising from said plate adjacentsaid inner and outer walls, spaced inner and outer vertical pipesengaged with said inner and outer collars respectively and adapted forpassage through an opening or openings in the floor or floors of abuilding, acap plate resting on the outermost of said pipes and having arestricted central opening, depending collars engaging the inner andouter pipes respectively, the center of said cap plate having anupstanding discharge neck surrounding said restricted opening, and achimney supported by said cap plate, said neck fitting within saidchimney, the outermost of said `pipes having hot air discharge openings.

4. A heating system comprising spaced inner and outer walls and an airinlet for the space between them, means within the inner wallpermit-ting heating thereof toin turn heat the air between the twowalls, a horizontal plate resting on'the upper ends of said walls andhaving heat discharge openings'between them, a downwardly extendingflange on the outer edge of said plate and surrounding said outer wall,collarsrising from said plate adjacent said inner and outer walls,spaced inner and outer vertical pipes engaged with said inner and outercollars respectively and adapted for passage through an opening oropenings in the floor or floors of a building, a cap plate resting onthe outermost of said pipes and having a restricted central opening,depending collars on said plate engaging the inner and outer pipesrespectively, the collar engaging said inner pipe being elongated andforming a slip joint connection with said inner pipe to permit theexpansion and contraction of said pipe, an upstanding neck surroundingthe restricted central opening in said cap plate, a chimney supported bysaid cap plate, said neck fitting within said chimney, stay bolts passedthrough said outer pipe and having their inner ends slidably engagedwith said inner pipe whereby the latter is centered, but permited toexpand and contract, and valved air conducting pipes connected with thespace between` said outer and inner pipes.
